cn'r'rme DEVICE.

Application filed March 4, 1926.. Serial No. 92,190."

- My invention relates to cutting devices, particularly adapted for cutting column rules for printing newspapers or other printed matter. I

The objects of my invention are: first, to provide an efficient device of this class for cuttinv column rules or the like by a short stroke and light blow of the hand and whereby unnecessary movement and waste of energy are eliminated; second, to provide a device of this class whereby only limited thicknesses of material may be cut and such thicknesses of material as are employed in making column rules; third, to provide a device of this classwhereby the column rules or other similar strips of material may be easily inserted between the cutting members ,IfIOIl] the front side of the device with its one end against the measuring stop means;

3o column rules and fourth, to provide a device ofthis class having an inclined table for supporting the material to be cut and asquare-ed'ged cuttingmember, where-bythecutting members may 'bemade and cut from a long bar of the required cross-sectionffifth, to providea device of this class in which the cuttingmemhere: may. be easily. changed; sixth, to pro videas a whole a novelly constructed hand,

operated impact cutting device for cutting the l1ke;-seventh, to provide a device of this class which is particu- "larly simple and economical of construction, durable, and which will not readily deteriorate or get out of order.

will appear hereinafter, my invention consists of certain novel features of construction, combination and arrangement of parts and portions, as will be hereinafter described indetail and particularly set forth in the appended claims, reference being had to the accompanyingdrawings and to the characters of reference J a partof this application, inwhich:

: Figure-l isa front. side view offmy cutting device; Fig. 2 isan end view thereof; Fig

Fig.1; Fig. 4 is afragmentary end elevational view thereof, taken from the opposite. endgof the device and on the 11116 wof Fig; 1, and Fig.5 is'a fragmentary sectional elevational view thereof, taken "through '5- 5 of Fig. 3.

With" these andother objects in View, as.

thereon, which form Like characters of reference refer to simi lar parts and portions throughout the-several views of the drawings.

The 1113111 support of my cutting device consists of a base member 1 having sup porting legs atwits opposite ends, cutting members at its one end and a measuring stop or gageintermediate its ends. At the upper side of the base member 1 is provided a backwardly and downwardly in clined supporting surface 1 upon which the column rules, or other material to be cut,

are positioned. At the back side of the supporting surface is provided an upwardly 7 extending ledge 1 which serves asa back stop andratthe upper side of whichisj'inscribed or otherwise appropriately applied-a 1, whiehl extends upwardly from thie supporting surface of the base member and forwardly'from the backledgethereof. This yoke corisistsof a pair. of upright members, .the one pos tioned forwardly :from the other and connected with each other by means of 'measuring scale 1 which," for 'cuttinicolunin rules, 1s graduated intopicas, as shown. yAtthe one end of the basemember is a yoke horizontal crossportions l The forward upright member of the yoke is spaced' upwardly from the supporting surface 1 of the base member providing a clearance, in-

dicated by 1 in Figs. 2,;4 and5, to permit the IIISQI'lDiOIl of the column rules or other; members-to be out between the cutting members of the device from the :front side there- Atthe "one end of the base below the yoke is secured, meansof pins 3 and screws 4;, a euttingmemberor plate 2. This cutting member is laterally positioned in a slot at said i one end of the base member. Said cutting member is beveled at its upper edge downwardly toward the supporting surface of the :base member and ispositioned with its keen cutting edge aslight distance above the supporting surface of the base "memberyas shown best in li igi 5. The for ward end of the cutting edge is beveledat its lower end with a cutting member 7,

of the yoke 1 is backwardly so as. to provide ready, insertion said plunger rodbeing screwed at its lower end into said cutting member and retained in position thereon by means of a set screw 8. The knob 6 serves as a means for forcing the cutting member downwardly as well as the stop at its lower end against the upper cross portion 1* of the yoke. The cutting member 7 is reciprocally mounted in a vertical direction in a slotted portion 1 at the lower end of the yoke. Said cutting member 7 is retained in position in the slotted portion of the yoke by means of a pair of-plates 9 and 10 secured, by means of screws 11, to the outer side of the yoke at the end of "the base member. Around the plunger rod 5 and between thecross portions 1 of the yoke is positioned a compression spring 12, which bears at its upper end against the lower end of a'collar13 secured to the plunger rod intermediate the cross portions 1 of the yoke and normally forces the cutting member 7 and the knob 6 in their respective upper positions;

Thelower portion of the cutting member '7 is beveled upwardl and outwardly, forming a cutting edge directly over the cutting edge of the member 2. The cutting edge of the member 7 is perpendicular with the" attached operating plungerrod 5, thus permitting the cutting member 7 to be made from a long cutting bar, which may be carried in stockand readily out and fitted to,

the cutting device for replacing the cutting member 7. i g

Over the supporting surface of the base member is positioned a measuring stop member 14, which is provided at its rear portion and lower side with a guide slot 14 for receiving the back ledge 1 of the base memrangement of parts and portions, I do not 'WlSh/EO bellmlted to thls part'lcular construction, combination and. arrangement, but

the side of which adjacent the cutting members the one ends ofcolumnrules or other members to be cutmay befpositioned for cutting said columnrules or:other members to even lengths.

Though I have shown and described a part cular construction, comblnationand ardesire to include'in the scopeof my invention the construction, combination and ar-' 'rangement substantially as set forth inthe appended claims.
